Leica V-Lux 3 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Olympus 7040 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features TruePic III processor.
Below you can see the V-Lux 3 and 7040 sensor size comparison.
Sensor Size and Resolution Comparison image of Leica V-Lux 3 and Olympus 7040 Cameras
Leica V-Lux 3 and Olympus 7040 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Leica V-Lux 3
or the
Olympus 7040 ,
including hyperfocal distance.
